@glyn.hudson - is the Node-RED port correct?

glyn.hudson · 2016-05-03T18:09:41.670Z

Been fixed , thanks. Should be 1880

Jon · 2016-05-03T19:17:24.600Z

To Glyn and the OEM Team - thank you for all of your efforts creating the new release! I’ll be updating to the emonSD-03May16 release later today!

I’m unable to complete the download of this file. It bombs out at around 1GB with a “Interrupted (NETWORK_FAILED)” message.
Anyone else getting this? Is there an alternate link I can try?

Cheers.

Xino · 2016-05-04T13:37:46.409Z

OK… after many many restarts I finally manged to download the file.
As a test I tried with the 8GB_emonSD-29Apr16.img.zip file and that downloaded fine. Server problems?

glyn.hudson · 2016-05-04T23:45:49.782Z

Oh dear, sorry to hear. We have not been aware of any server issues. The image is served from the same server as this forum and the main site.

Could you try and download via http as opposed to https and confirm if issues persists?

Tried an http download. The transfer went end-to-end without issue.

glyn.hudson · 2016-05-05T00:47:40.658Z

That’s interesting, The download link in the post above has always been http. Does it auto resolve to https for you?

Bill.Thomson · 2016-05-05T02:24:42.786Z

glyn.hudson:

I don’t think so. Mousing over it gives me: http://openenergymonitor.org/files/emonSD-03May16.img.zip

This time, I did the transfer at home, so different computer ISP, everything.

The earlier transfers were done from my office. We do share the WiFi “campus-wide” so to speak, but it’s a 50 Mb pipe to the internet backbone, possibly a 100 Mb link, not sure. I know that it runs much faster than the 18 Mb link I have at home.
The one thing in common each time the transfer stopped was the byte count. Both times it was at 1.0 GB when it aborted.

Robert.Wall · 2016-05-05T08:29:12.146Z

Hmm. Stopping at the same place, on a round number? I smell an artificial limit.

glyn.hudson · 2016-05-05T09:03:06.126Z

Anyone else noticed this issue with download hanging? Maybe temporary glitch? Again downloading ok for me at home this morning over adsl

Issue still occurring here.

I tried to download again, via the link above and http and both ways interrupted at around 1GB.

Tried this morning and indeed it stops after 1 Gb … isn’t there a cap on download in ftpd ?
No problem to relaunch and continue the download.

glyn.hudson · 2016-05-05T12:02:51.713Z

Ok, I have just been able to replicate the issue at work. Very strange. I have posted an alternate server mirror download link as an alternative. Is anyone able to host another mirror for us? Ideally in the USA? @Bill.Thomson?

I will have to investigate. I think the issue is could be due to HTTPS and cloudflare.

pb66 · 2016-05-05T12:13:06.934Z

Have you considered using GitHub’s LFS?

glyn.hudson · 2016-05-05T13:06:24.472Z

ok, I think issue should be fixed. I created a page rule on Clodflare to disable caching in the /files folder. I have just been able to complete a download at work.

No, but looks interesting. I don’t think it would have helped solve this issue but would be since we could host the large image file on a remote server while tracking changes for the image file in the emonPi repo on github. I will have a go at setting this up.

Nope , still stops at around 1GB.

glyn.hudson · 2016-05-05T14:40:49.859Z

Would you mind trying again?

I’ve just white listed cloudflares IP addresses which act as a proxy. I think our web server thought it was under attack do the high volume of traffic funnelled through these IP’s. They should now be white listed so should not be limited any more.

Working on it. We changed hosts, and for some reason, I’m not (yet) able to get it working (permissions issue) Will let you know when it’s ready.

Issue resolved. files are available via both HTTP and FTP from the USA mirror. HTTP link and FTP info are at the top of this thread.
